Specification of Letters Patent.

Application filed lei-i126, 1811. Seriall'o. 628,417.

To all whom it may concern:

Be itknown that I; WILLIAM F. SHORE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gages, of which the following is a full, clear, and exact specification.

This invent-ion relates to gages, designed specially for testing rubber or other resilition proceeds.

drawings, in which Thls invention comprisessuch parts and combinations as are hereinafter set forth, while reference is had to the accompanying Figure 1 -=is a front elevation, partly in section, of a gage embodying my invention, with the cover removed; and Fig. 2 is a vertical sectional view of the gage shown in Fig. 1.

Referring to the drawings, 5 represents a circular casing and 6 a cover therefor, having an opening protected by a glass or celluloid cover 7, through which a scale may be observed. A bearing block 17 is extended inwardly beyond the center of the casing 5 and is slotted at 18 for the reception of the pinion 19 and a toothed rocker 20, which latter is pivoted to one side of the axial line to the bearing block 17. The bearing block 17 is held in place between the cover 6 and the circular casing 5 by means of screws 10, 10, one of which constitutes the pivot for said rocker.

22 is a measuring pin for operating the rocker 20 against the resistance of the spring 23.

When the measuring pin is pushed in- Wardly, the rocker 20 is oscillated, which, in turn, rotates the pinion 19 to operate the pointer 24 and which pointer registers on the scale 25. 1

In this construction, the scale may be made many times longer, without increasing I the size of the instrument, than it is possible to do when no means is employedfor multiplying this movement. The gage shown n this construction is also provided with a locking pin having a shank- 26, a thumb piece or knob 27 and a spring 28-located between the thumb piece and the back of the covering on the bottom of the casing, for holding the locking pin out of normal engagement with the rocker 20.

When it is desired to ascertain and meas ure the recovering and resilient qualities of the rubber or other substance, the locking pin is pushed inwardly against the resistance of the spring 28 until said pin abuts the rocker 20 and thus prevents said rocker from'oscillating when the pin 22 is pressed or forced into the rubber or othersubstance to be measured, toits full exposed length. It will be understood, however, that the pin 22 does not penetrate or cut into the rubber or other substance. When said pin 22 has been thus pressed into the rubber or othersubstance, the locking pin above described is released and as the substance regains its normal or original form it pushes the pin 22 inwardly in the gage, thereby oscillating the rocker 20, which rotates the pinion 19 and which pinion, in turn, causes the indicator 24 to register on the scale 25, and in this way the recovering tendency or resilient qualities of the rubber or other substance tested is registered in degrees on said scale 25, as explained. In this instance, however, the spring 23 is one of less resistance than the spring would be if the gage were used merely for testing or measuring the yielding qualities of the rubber or other substance, and, likewise, the pin 22 may be more pointed than a pin used in a "gage for measuring the yielding qualities of the substance, as above stated. 7

It will also be understood that I do not limit myself to the exact construction and arrangement of parts shown in the drawings and described in thespecification, as it is obvious that various changes and modifications may be made and different materials used, without departing from the spirit and scope of my invention.

Having thus describedmy invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a gage of the character described, the combination of a circular casing, a cover for the same having an openingprotected by or celluloid covering, a hearing hloch. inserted within sad casing and profleeting in a radial direction within the same, said bearing block being provided withv a slot, a measuring pin pro ecting into said slot, a pointer, a toothed rocker and a pinion engaging said toothed rocker for operating said pointer by an inward movement of the said measuring pin, substantially as shown and described.

2,. in a gage of the character described,

the combination of a circular casing and a cover therefor, a measuring pin located. partly within and partly without the ga e,

a pointer, means embodying a rocker or transmitting movement of the measuring pin to the pointer, and locking means normally out of engagement with said rocker for preventing movement of the rocker and pointer x a gage of the character descrlbed, the combinatlon of a circular casing and a cover therefor, a bearing block in said casing and projecting in a radial direction within the same, provided with a slot, a measuring pin projecting into said slot, a pointer, a toothed rocker, a inclining pin provided with means said bearingblock being V anaagiai for keeping said pin out of normal engagement with said rocker, and a pinionengaging said toothed rocker toroperating said polnter by an inward movement of the said measuring pin, substantially as'shown and described.

4. In a gage of the character described, the combination of a circular casing and a cover therefor, a bearing block in said casing and projecting in a radial direction within the same, said bearing block being provided with a slot, a measuring pin projecting into said slot, a pointer, a toothed rocker provided with a spring for keeping said rocker in its normal position, a'manually-operated 1 locking pin adapted to abut said toothed rocker for preventing said rocker from oscillating, and a pinion engaging said toothed rocker for operating said'pointer by an inward movement of said measuring pin when said locking pin is released, substantially as shown and described.

In testimony whereof; I afix my signature, in presence of two witnesses.
